SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2015–03–01,
Amendment 39–18097 (80 FR 7298,
February 10, 2015) (‘‘AD 2015–03–01’’).
AD 2015–03–01 applied to all
Bombardier, Inc. Model CL–600–2B19
(Regional Jet Series 100 & 440)
airplanes. The NPRM published in the
Federal Register on June 8, 2016 (81 FR
36813). The NPRM was prompted by
updates to the weight and balance data
needed to calculate the center of gravity
for affected airplanes. The NPRM
proposed to continue to require
installing additional attaching hardware
on the left and right engine fan cowl
access panels and the nacelle attaching
structures. The NPRM also proposed to
require weight and balance data to be
included in the Weight and Balance
Manual and applicable logbooks for
certain modified airplanes. We are
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
issuing this AD to prevent damage to the
fuselage and flight control surfaces from
dislodged engine fan cowl access
panels, and prevent incorrect weight
and balance calculations. Incorrect
weight and balance calculations may
shift the center of gravity beyond
approved design parameters and affect
in-flight control, which could endanger
passengers and crew.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2014–20R1,
dated August 12, 2015 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for all Bombardier, Inc. Model CL–600–
2B19 (Regional Jet Series 100 & 440)
airplanes. The MCAI states:
There have been a number of engine fan
cowl panel dislodgement incidents reported
on the Bombardier CL–600–2B19 aeroplane
fleet. The dislodged panels may cause
damage to the fuselage and flight control
surfaces of the aeroplane. Also, the debris
from a dislodged panel may result in runway
contamination and has the potential of
causing injury on the ground.
Although the majority of the subject panel
dislodgements were reported on the first or
second flight after an engine maintenance
task was performed that required removal
and reinstallation of the subject panels, the
frequency of the dislodgements indicates that
the existing attachment design is prone to
human (maintenance) error.
In order to mitigate the potential safety
hazard of the subject panel dislodgement,
Bombardier had issued Service Bulletin (SB)
601R–71–034 to install additional fasteners
for the attachment of the engine fan cowl
panels to the nacelle’s structure. Compliance
of the above SB was mandated by the original
issue of [Canadian] AD CF–2014–20 dated 9
July 2014 [which corresponded to FAA AD
2015–03–01].
Bombardier has now revised the SB 601R–
71–034 (to Revision C) requiring weight and
balance data to be included in the Weight
and Balance manual for aeroplanes modified
per the subject SB. This revised [Canadian]
AD is issued to mandate compliance with SB
601R–71–034, Rev C.
Required actions also include the
retained actions of modifying the engine
fan cowl access panel. You may
examine the MCAI in the AD docket on
the Internet at https://
www.regulations.gov by searching for
and locating Docket No. FAA–2016–
6897.
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comment
received on the NPRM and the FAA’s
response.
E:\FR\FM\12APR1.SGM
12APR1
Federal Register / Vol. 82, No. 69 / Wednesday, April 12, 2017 / Rules and Regulations
Request To Refer to Revised Service
Information
Related Service Information Under 1
CFR Part 51
Air Wisconsin Airlines requested that
we revise the NPRM to refer to
Bombardier Service Bulletin 601R–71–
034, Revision D, dated October 7, 2016.
Air Wisconsin also asked that we add
Bombardier Service Bulletin CF34–
NAC–71–042, Revision C, dated
September 4, 2016. Air Wisconsin stated
that the hardware kits are identified in
this service information.
We partially agree with the
commenter’s request. No additional
work is required by Bombardier Service
Bulletin 601R–71–034, Revision D,
dated October 7, 2016; it merely adds
notes for clarification and contains
minor editorial changes. Since
Bombardier Service Bulletin CF34–
NAC–71–042, Revision C, dated
September 4, 2016, is a secondary
source of service information, it is not
referenced in this AD.
We have revised the Related Service
Information under 1 CFR part 51 section
of the preamble and paragraphs (g) and
(h) of this AD to refer to Bombardier
Service Bulletin 601R–71–034, Revision
D, dated October 7, 2016.
We have also redesignated paragraph
(i) of the proposed AD as paragraph
(i)(1) of this AD, and added credit for
actions required by paragraph (g) of this
AD if accomplished prior to the
effective date of this AD using
Bombardier Service Bulletin 601R–71–
034, Revision C, dated May 8, 2015.
We have also added paragraph (i)(2)
to this AD to provide credit for actions
required by paragraph (h) of this AD if
accomplished prior to the effective date
of this AD using Bombardier Service
Bulletin 601R–71–034, Revision C,
dated May 8, 2015.
Bombardier, Inc. has issued Service
Bulletin 601R–71–034, Revision B,
dated August 1, 2014; and Service
Bulletin 601R–71–034, Revision D,
dated October 7, 2016. The service
information provides procedures for
modifying the engine fan cowl access
panels and the nacelle attaching
structures. These documents are distinct
because Service Bulletin 601R–71–034,
Revision D, dated October 7, 2016, also
includes weight and balance
information. This service information is
reasonably available because the
interested parties have access to it
through their normal course of business
or by the means identified in the
ADDRESSES section.
Clarification of Alternative Methods of
Compliance (AMOCs) Paragraph
We have revised paragraph (j)(1)(ii) of
this AD to clarify that Global AMOC 15–
36, dated August 28, 2015, is approved
for the corresponding provisions of
paragraph (g) of this AD.

Conclusion
We reviewed the available data,
including the comment received, and
determined that air safety and the
public interest require adopting this AD
with the changes described previously
and minor editorial changes. We have
determined that these changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

Costs of Compliance
We estimate that this AD affects 497
airplanes of U.S. registry.
The actions required by AD 2015–03–
01 and retained in this AD take about
8 work-hours per product, at an average
labor rate of $85 per work-hour.
Required parts cost about $5,458 per
product. Based on these figures, the
estimated cost of the actions that are
required by AD 2015–03–01 is $6,138
per product.
We also estimate that it will take
about 1 work-hour per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Based on these figures,
we estimate the cost of this AD on U.S.
operators to be $42,245, or $85 per
product.
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
section 106, describes the authority of
the FAA Administrator. ‘‘Subtitle VII:
Aviation Programs,’’ describes in more
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in ‘‘Subtitle VII,
Part A, Subpart III, Section 44701:
General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.

Regulatory Findings
We determined that this AD will not
have federalism implications under
Executive Order 13132. This AD will
not have a substantial direct effect on
the States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify that this AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in
Alaska; and
4. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2015-03-01, Amendment 39-18097 (80 FR 7298,
February 10, 2015) (``AD 2015-03-01''). AD 2015-03-01 applied to all
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440)
airplanes. The NPRM published in the Federal Register on June 8, 2016
(81 FR 36813). The NPRM was prompted by updates to the weight and
balance data needed to calculate the center of gravity for affected
airplanes. The NPRM proposed to continue to require installing
additional attaching hardware on the left and right engine fan cowl
access panels and the nacelle attaching structures. The NPRM also
proposed to require weight and balance data to be included in the
Weight and Balance Manual and applicable logbooks for certain modified
airplanes. We are issuing this AD to prevent damage to the fuselage and
flight control surfaces from dislodged engine fan cowl access panels,
and prevent incorrect weight and balance calculations. Incorrect weight
and balance calculations may shift the center of gravity beyond
approved design parameters and affect in-flight control, which could
endanger passengers and crew.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-20R1, dated August 12, 2015 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for all Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes. The MCAI states:
There have been a number of engine fan cowl panel dislodgement
incidents reported on the Bombardier CL-600-2B19 aeroplane fleet.
The dislodged panels may cause damage to the fuselage and flight
control surfaces of the aeroplane. Also, the debris from a dislodged
panel may result in runway contamination and has the potential of
causing injury on the ground.
Although the majority of the subject panel dislodgements were
reported on the first or second flight after an engine maintenance
task was performed that required removal and reinstallation of the
subject panels, the frequency of the dislodgements indicates that
the existing attachment design is prone to human (maintenance)
error.
In order to mitigate the potential safety hazard of the subject
panel dislodgement, Bombardier had issued Service Bulletin (SB)
601R-71-034 to install additional fasteners for the attachment of
the engine fan cowl panels to the nacelle's structure. Compliance of
the above SB was mandated by the original issue of [Canadian] AD CF-
2014-20 dated 9 July 2014 [which corresponded to FAA AD 2015-03-01].
Bombardier has now revised the SB 601R-71-034 (to Revision C)
requiring weight and balance data to be included in the Weight and
Balance manual for aeroplanes modified per the subject SB. This
revised [Canadian] AD is issued to mandate compliance with SB 601R-
71-034, Rev C.
Required actions also include the retained actions of modifying the
engine fan cowl access panel. You may examine the MCAI in the AD docket
on the Internet at https://www.regulations.gov by searching for and
locating Docket No. FAA-2016-6897.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the NPRM and
the FAA's response.
[[Page 17541]]
Request To Refer to Revised Service Information
Air Wisconsin Airlines requested that we revise the NPRM to refer
to Bombardier Service Bulletin 601R-71-034, Revision D, dated October
7, 2016. Air Wisconsin also asked that we add Bombardier Service
Bulletin CF34-NAC-71-042, Revision C, dated September 4, 2016. Air
Wisconsin stated that the hardware kits are identified in this service
information.
We partially agree with the commenter's request. No additional work
is required by Bombardier Service Bulletin 601R-71-034, Revision D,
dated October 7, 2016; it merely adds notes for clarification and
contains minor editorial changes. Since Bombardier Service Bulletin
CF34-NAC-71-042, Revision C, dated September 4, 2016, is a secondary
source of service information, it is not referenced in this AD.
We have revised the Related Service Information under 1 CFR part 51
section of the preamble and paragraphs (g) and (h) of this AD to refer
to Bombardier Service Bulletin 601R-71-034, Revision D, dated October
7, 2016.
We have also redesignated paragraph (i) of the proposed AD as
paragraph (i)(1) of this AD, and added credit for actions required by
paragraph (g) of this AD if accomplished prior to the effective date of
this AD using Bombardier Service Bulletin 601R-71-034, Revision C,
dated May 8, 2015.
We have also added paragraph (i)(2) to this AD to provide credit
for actions required by paragraph (h) of this AD if accomplished prior
to the effective date of this AD using Bombardier Service Bulletin
601R-71-034, Revision C, dated May 8, 2015.
Clarification of Alternative Methods of Compliance (AMOCs) Paragraph
We have revised paragraph (j)(1)(ii) of this AD to clarify that
Global AMOC 15-36, dated August 28, 2015, is approved for the
corresponding provisions of paragraph (g) of this AD.
Conclusion
We reviewed the available data, including the comment received, and
determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Bombardier, Inc. has issued Service Bulletin 601R-71-034, Revision
B, dated August 1, 2014; and Service Bulletin 601R-71-034, Revision D,
dated October 7, 2016. The service information provides procedures for
modifying the engine fan cowl access panels and the nacelle attaching
structures. These documents are distinct because Service Bulletin 601R-
71-034, Revision D, dated October 7, 2016, also includes weight and
balance information. This service information is reasonably available
because the interested parties have access to it through their normal
course of business or by the means identified in the ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 497 airplanes of U.S. registry.
The actions required by AD 2015-03-01 and retained in this AD take
about 8 work-hours per product, at an average labor rate of $85 per
work-hour. Required parts cost about $5,458 per product. Based on these
figures, the estimated cost of the actions that are required by AD
2015-03-01 is $6,138 per product.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD on U.S. operators to be $42,245, or $85 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
